Toph, the First Metalbender + Toph, Hardheaded Teacher + Thaumatog + Orzhov Basilica

Toph, the First Metalbender

Toph, Hardheaded Teacher

Thaumatog

Orzhov Basilica

How it works

1. Cast the artifact by paying 0.
2. Toph, Hardheaded Teacher triggers, earthbending Orzhov Basilica.
3. Resolve the artifact spell.
4. Activate Thaumatog by sacrificing Orzhov Basilica.
5. When Orzhov Basilica dies, Toph, Hardheaded Teach triggers, returning Orzhov Basilica from your graveyard to the battlefield tapped.
6. When Orzhov Basilica enters, it triggers, returning the artifact cast in step 1 from the battlefield to your hand, as it's a land due to Toph, the First Metalbender.
7. Resolve the Thaumatog ability
8. Repeat.

This clever loop turns the static ability of Toph, the First Metalbender into a brilliant rules interaction, transforming your cheap artifacts into land permanents that bounce themselves repeatedly. You cast your zero-mana artifact to trigger Toph, Hardheaded Teacher, which earthbends Orzhov Basilica into an animated land creature ready to be sacrificed to Thaumatog for a power boost. Because Orzhov Basilica was a land when it died, its delayed return trigger brings it right back to the battlefield tapped, where its own enter-the-battlefield ability triggers to return the original artifact back to your hand for another go-around.
